I didn't bring my ID card when I stayed in the hotel today, which shows that the population database is abnormal. What happened?

I didn't bring my ID card when I stayed in the hotel, indicating that the abnormal population database may be a system failure.

Then restart the system and try again. If you don't have an ID card when staying in a hotel, you can report your ID number to the police station in the hotel area. The staff will check the identity of the personnel approved by the national population information system and issue temporary identity certificates in time for them to stay in the hotel.
